Ok so I have a Chevy traverse 2011 with about 22k miles, automatic. The problem is my check engine light is on, thought I might need a spark plug replacement but that wasn’t it. The check engine light came off after the replacement but it came back on again later on that day. So the check engine light and there also seems to be some sort of vibration when I’m breaked at a red light. The vibrating doesn’t occur when I’m breaking but more so once I’ve come to a complete stop. My rpm meter also jumps during this vibration while I’m breaked. Do you have any clue what might be wrong ?

Realize our thousands of reason your check engine light can come on. But give me the actual code like PO171 so I can analyze it
